Another source has told me that you cannot use the Phono input on a reciever for anything other than a turntable. Is there any truth to this? The reason being:
1. There is no turntable (lol)
2. I have one more source to put onto the reciever and no other inputs available.

The reciever I Have to work with is a generic $400.00 Sony (I don't have the model number)
